Thank you for viewing! (_ _) Are you having trouble with broken or missing connecting parts? These are 3D-printed replacement connecting parts. While we haven't lost any, we replaced the ones that were loose and kept falling off! These are exclusively for the E5 series Hayabusa. Please note that they cannot be installed on the E6 series Komachi. However, they can be installed on the MAX, although the tip shape is different. Set Contents: E5 series Hayabusa connecting part x1 E5 series Hayabusa connecting part cover x1 Dedicated connecting parts x2 (including replacements for when broken) The couplers are basically female type. If you comment, I can post photos of the male type couplers, and I can change them. Feel free to ask (*_ _) One male and one female are also possible. If you want spares, please comment. You can add them for 30 yen each, regardless of male or female. *Vehicles are not included in the set. Please prepare them yourself. The color is based on the Hayabusa, but it's slightly different. Please consider it as amateur painting. If you don't need the paint, please comment. *Even if the connecting part is damaged, it can be easily replaced by removing the screws. Please tighten the screws gently. They will strip easily.
